It's a fact that all, not countless, strategies will fail in the long run. That's why there's such a thing as a house edge.
Almost any strategy can and will work in the short term, just a matter of when it will fail users.
I'm just getting to understand the concept of house edge. It seems a little like an insurance policy to ensure a certain amount of profits go to the house.
Do you think this can be implemented in actual games like sports, animal races etcetera? Or those depend solely on bookmarkers who set the odd to reduce the probability (or amount) of winnings based on possible predictions.
